upgraded fuel spider

Im going to replace my spider with an upgraded one. Here are the ones i found:
BWD part # 63886
DELPHI Part # FJ10566
ACDELCO Part # 2173029
I just want to know which one is the best. The price is not a big deal I just want to know what you guys have used and what is going to give me the best results as far as fuel economy and power. I'm obviously going to do all the gaskets when i replace it.
Thanks

GM trucks love GM parts. So I would go with the Delco. I have not done this upgrade yet but looking it to it the Delco had amazing reviews people saying it breathed new life to their truck or they gained a couple mpg.

yea thats what ive always heard too. i take back what i said on the cost tho. the delco is about 150$ more than the others and i would rather not go that high. im leaning towards the delphi i think

i recommend doing the swap reguardless because it will defrease the chance of carbon buildup on the injections a LOT. and in the long run it will be more efficent.

yea my truck idles pretty rough and it smells like un burnt fuel when its idling and it pops and shutters when it idles. It also is pretty low on power. I'm pretty sure its this spider and I'm gonna do cats next. Thanks for the replies

Yea I had to replace my distributer about 6 months ago and It came with a cap and rotor. I also did wires shortly before that but I exchanged them for better ones when i did the distributer because I noticed the old ones shorting out. The only thing is I was way tight on funds and bought the cheapest stuff I could to get me on the road again. but when i orded the spider yesterday I ordered acdelco cap rotor and wires. So hopefully she will run like a top.
